The Middle (MP) and Early Upper Paleolithic (EUP) evidences of shellfish collection on the southern Iberian site of Bajondillo cave are presented and compared with Westernmost Mediterranean archaeological sites. The main feature is stasis for Mytilus galloprovincialis represents the dominant taxon during a ∼120kyr temporal sequence. The second feature is the decrease of the shellfishing signal when site distance to the coast increases. The data reveal that shellfish collection was practiced during Marine Isotopic Stage 4, a poorly documented stage in terms of aquatic adaptations. Striking is also that mollusc assemblages evidence an uninterrupted decreasing trend in terms of remains from the earliest to the latest levels, in particular when H. sapiens replaced H. neanderthalensis. Although taxa of secondary importance are too scarce to make reliable inferences, another difference between the MP and EUP collections is the substantial increase of infaunal bivalves in the latter cultural period. Warm and cold water mollusc records match temperature rises and drops although the scarcity of data do not allow one to proceed beyond qualitative statements. Likewise, the prevalence of fresh and brackish water mollusc hint at a permanent presence of freshwater around the site at all times. When compared with assemblages from the Alboran sea region (Westernmost Mediterranean Sea), the Bajondillo cave collections are remarkable for their abundance of mussels. Comparison between Bajondillo cave and Pinnacle Point reveal that infaunal bivalve abundances in the South African site are far higher than those recorded in the MP levels, though not those from the EUP. Whether this feature hints at subtle differences existing between the collection of shellfish by H. sapiens and H. neanderthalensis , reflects a behavioral convergence between the two hominine lineages or represents an inherited cognitive trait from a common ancestor is an issue in need of further analysis. • Decreasing trend in terms of mollusk remains from the earliest to the latest levels, increase at MP/EUP transition. • Substantial increase of infaunal bivalves during the Upper Paleolithic. • Certain correlation existing between the shellfishing signal with distance to coast and paleoenviromental conditions. • Bajondillo's unique feature being an outstanding abundance of mussels. • Potential convergent evolution in the so-called Mediterranean biomes.

The prevalence of large game found in association with Middle Paleolithic tools has traditionally biased our ideas of Neanderthal subsistence practices. Studies document the exploitation of small mammals, birds, and plants by Neanderthals, whereas data on aquatic resources are still scarce and data on fish are almost non-existent. This article presents a review of fish remains from 11 Middle Palaeolithic fish bone assemblages from well contextualized sites in Belgium, France and Spain. It explores the nature of the evidence in order to determine whether Neanderthal fished and if so, whether fishing was a casual, opportunistic activity or a systematic practice. The first issue to address is whether archaeological fish remains at any given site represent human activity or not. Our study tests that assertion while enhancing our understanding of the diversity of food alternatives available to Neanderthals at any given site, and their ability to adapt to them. Methodological protocols include quantification, body mass and length estimations, and, whenever possible, spatial distribution of fish remains, taphonomic analyses and inference of the season of death. This methodology constitutes an analytical protocol to assess the contribution of fish to the human diet during the Paleolithic and set apart human-generated fish deposits from those generated by alternative fish accumulators. The evidence gathered so far points essentially to circumstantial fishing by Neanderthals, and the question must necessarily remain open for the moment. Nevertheless, some of the evidence, in particular the presence of large (>1 kg) fish in anthropogenic deposits and the absence of animal digestive traces and gnawing marks on fish bones in such deposits, seems compelling and suggests that Neanderthals could have played a role in the accumulation of some of these remains. • This paper explores the evidence of Neanderthal fishing. • If such fishing was a casual, opportunistic activity or a systematic practice. • Review of fish remains from 11 Middle Palaeolithic contextualised freshwater fish deposits. • Large (i.e. > 1kg) fishes in anthropic deposits and absence of animal digestive traces and gnawing marks. • Neanderthals could have played a role in the accumulation of part of these remains.
